Zedeyes 3108  Pressure Transmitter

The Zedeyes 3108 is a heavy-duty, high-performance industrial pressure transmitter built around an advanced diffused-silicon piezoresistive OEM sensing core. Designed for severe outdoor and heavy industrial environments, every 3108 transmitter undergoes rigorous thermal aging and long-term stability testing to ensure high reliability across demanding process control loops, oilfields, and municipal gas networks.

Enclosed in a rugged, low-copper aluminum alloy housing with an SS316L sensing diaphragm and SS304 process port, the Model 3108 offers flexible signal communication options—including standard 4–20 mA, HART protocol, and RS485 digital output. Optional local display modules and field zero/span adjustments allow convenient on-site setup and diagnostic inspection.

Key Features & Benefits

• High-Performance Diffused-Silicon Core: High-sensitivity piezoresistive sensor provides exceptional dynamic response, minimal hysteresis, and superior long-term stability ($\pm0.2\%\text{ FS/year}$).

• Extreme Mechanical Shock & Vibration Resistance: Tested to IEC standards for sine vibration ($20\text{ g}$), random vibration ($7.5\text{ g}_\text{rms}$), and high mechanical shock ($100\text{ g}$ / 1-meter free fall resistance).

• Versatile Signal & Communication Options: Available with standard 4–20 mA current loop, digital HART protocol, or RS485 Modbus digital communications for seamless integration into modern DCS and SCADA networks.

• Broad Range Capabilities: Covers extensive pressure spans from ultra-low and vacuum pressures (−100 kPa) up to extreme high pressures (100 MPa).

• Advanced EMC Noise & Surge Immunity: Features built-in surge protection ($2\text{ kV}$ per IEC 61000-4-5) and ESD immunity ($15\text{ kV}$ air discharge per IEC 61000-4-2) against industrial electrical disturbances.

• Optional Local Display & Field Adjustability: Configurable with a local LCD/LED display module and zero/span calibration capability for simplified field servicing.

Primary Applications

• Oil Fields & Heavy Industry: Wellhead monitoring, hydraulic power units, blowout preventers, and heavy industrial machinery.

• Petrochemical Plants & Gas Pipelines: Refineries, natural gas metering stations, and chemical processing networks.

• Industrial Process Control: Closed-loop pressure regulation, compressor stations, and automated machine building.

• Water Supply & Utilities: Municipal water distribution, booster pumping stations, and wastewater treatment headers.
